NTSC camera streaming MJPEG over the network

[Charlie X. Liu]

I used Sensoray Model 811 <http://www.sensoray.com/products/811.htm> /911
<http://www.sensoray.com/products/911.htm> /614NC
<http://www.sensoray.com/products/614.htm> /314NC
<http://www.sensoray.com/products/314.htm>  (capturing raw and compressing
with MJPEG) to stream over IP using GStreamer. It worked pretty good, and
the commands are:

 

Streaming Server: (IP=10.140.1.35)

$ gst-launch-0.10 v4l2src device=/dev/video0 ! videorate ! capsfilter
name=vfps caps=\"video/x-raw-yuv,framerate=30/1\" ! ffmpegcolorspace !
jpegenc ! multipartmux ! tcpserversink-sinkhost=127.0.0.1 port=5000

 

Streaming Client: (IP=10.140.5.23)

$ gst-launch-0.10 tcpclientsrc host=127.0.0.1 port=5000 !multipartdemux !
jpegdec ! autovideosink

$ gst-launch-0.10 tcpclientsrc host=10.140.1.35 port=5000 !multipartdemux !
jpegdec ! autovideosink

or

$ vlc tcp://127.0.0.1:5000 (local)

$ vlc tcp://10.140.1.35:5000 (overIP)

what is the gst-launch stdout/stderr ?

gst-launch is running silently or doesn't run ?

perhaps your sound card is used by another application for playback ?
